Event Description

It was reported during an unknown procedure that the curved cup inserter is cross threaded.The cup would not disengage from the inserter.The cup was pulled out and removed, and put on a straight handle for insertion.It is unknown if there were any health consequences or impact.

Manufacturer Narrative

The complaint sample was returned incomplete to viant for evaluation and the reported event is unconfirmed.The offset cup impactor was returned without the removable nose (impactor tip) and had functioned when threading on and off a cup fixture using a test impactor tip numerous times without fail as intended.To evaluate the reported failure, the function of the device was checked using a cup fixture per the viant impactor function and resistance test work instruction.The device was able to thread on and off and cup fixture numerous times without any issues or complications.A test impactor tip was utilized as the impactor tip was not returned and the offset cup impactor is intended to be used with it to perform its intended purpose.It is unknown whether or not the impactor tip was used during the surgical procedure.If the device was used without a removable nose (not the intended use), the ratchet mechanism would have to be tightened/ratcheted down to an extreme degree, which is not intended.This would likely lead to failures (fractures and/or deformations) and could had possibly led to the ratchet weld failure observed.The ratchet mechanism weld is cracked but not fractured all the way around.It is plausible for such an instance to have occurred as the ratchet teeth were observed to be worn suggesting the device could have been over-tightened.Per the above evaluation, the reported event is unconfirmed.The threaded tip shows no signs of deformation or damage from threading on and off the cup fixture.Further inspection of the device revealed the following other observations; · the impactor body nose has signs off damage/gouging which is not expected in this area.· the ratchet teeth show signs of wear from repeated use.· the impaction plate has experienced impacts from repeated use.· the chain is able to rotate freely within the impactor body without any friction.· the universal joints (uj) on the chain shows no signs of breakage or deformation.The ifu sent with this device today, man-004011 rev b, states the following; · offset cup impactors are hand-held, re-usable surgical instruments.· anticipated useful life offset cup impactor: 600 use cycles, · end of life is generally by wear and damage due to intended use, · visually inspect for damage and wear.If the instrument is damaged and worn, it is considered at the end of its life and should be discarded, · check hinged instruments for smooth movement, · when the udi carrier(s) is no longer readable, the instrument is to be discarded, · viant devices should only be used by qualified personnel fully trained in the use of the surgical instruments and the relevant surgical procedures, · do not modify viant instruments in any way and handle with care at all times.Surface scratches can increase wear and the risk of corrosion, · manual surgical instruments have a limited life-span which is determined by wear or damage due to repeated intended use.When a surgical instrument reaches the end of its functional life, clean the instrument of any and all biomaterial/biohazards and safely discard the instrument in accordance with applicable laws and regulations.The viant risk management files were reviewed to the reported failure mode is captured and assessed within the viant device history files (dhf).The review revealed there is a similar failure mode identified and mitigated to the lower possible risk region.The device history records (dhr) was reviewed and found no related manufacturing deviations or anomalies that would have contributed to the reported event.Assembly of the offset cup impactor with a cup fixture was verified at 100% frequency in operation 140 (assembly) & then 1 piece at operation 800 (final inspection) during the assembly level.This device had experienced approximately 4.77 years of use.It is unknown as to how many surgical procedures (cycles) this device had experienced throughout its life in the field.In conclusion, the reported event is unconfirmed since the returned offset cup impactor functioned when threading on and off the cup fixture numerous times without fail as intended.No further investigation with regard to this complaint is required.Viant will continue to monitor for trends.H6: updated type of investigation, investigations findings, and conclusions.
